<!DOCTYPE html>
<html lang="ja">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<%= yield(:metatag) if content_for?(:metatag) %>
<title>Nested Layouts</title>
<%= csrf_meta_tags %>
</head>
<body>
<%= content_for?(:content) ? yield(:content) : yield %>
<%= yield(:bottom) if content_for?(:bottom) %>
</body>
</html>- Create 2 index files in
app/views/static_pagesandapp/views/products - Put some text in that 2 file in
<% content_for(:content) do %>
